Stephen Tonkin - “Time and Calendars”

The measurement of time has always been a facet of Astronomy. The phases in the development of the Gregorian calendar most (but not all!) of us use today make a fascinating story which blends science, history, sociology, religion and psychology. From there we look at different ways of reckoning time, and examine the consequences of special relativity for time reckoning.

Stephen runs “The Astronomical Unit” which exists to make reliable astronomical information available to all. He does this through providing free information on the web site and undertaking outreach activities, including Star-tales (astronomy-based story-telling for children and adults), giving Astronomical Talks and running Astronomy Courses in the local community. These outreach activities are run both independently and in association with local astronomical societies, the National Trust, BBC Stargazing Live, local community groups, schools, colleges and adult learning centres.

The Vectis Astronomical Society meets on the 4th Friday of every month, except for December. This event is open for non-members to attend. The speakers come from all over the country and give a presentation for around 45 mins. We then stop for a break with tea and biscuits, which gives an opportunity to mingle and chat. The second half of the evening one of our regular members will give a short 20min ‘what’s in the sky this month’ presentation.

We have a suggested donation of £2.50 for Non Members of Vas
